Application inea Aprile, 1912. serial No. 688,064,

This tie 1 has a top flange Q being prefas shown, the ballast referredto. and a base flange 3, the latter erably arched on its underside toform a housing within which will pack.

4 is insulating material on and nnderlapping the top flanges 2, and'.5is ,a chair resting on said insulating material. is slightly wider thanthe'top flange 2 To all whom it may concern.'

Be it known that I, VILLIAM H. MORGAN, a citizen of the United States,residing at in the county of Stark and State of Ohio, have inventedcertain new and useful Improvements in Railroad-Track Construction; andI do hereby declare the following to be a. full, clear, and exactdescription of the invention, such as will'y enable others skilled inthe art to which' it appertains to make and use theV same. My inventionrelates to an improvement in railroad track construction, of' the typedisclosed in application Serial Number 639,446 filed by lV. V. Hartzelland myself July-18th, 1911. In the construction disclosed in the saidapplication, the spring clamps or clips bear directly against, and arein contact with the base flange of the rail. In the winter, itfreqnently'happens that the portions of the road bed exposed to the sunwill ,thaw ont, while the portion thereof shaded by trees and otherobjects will remain frozen. Vith the road bed in such condition, thetrack over the frozenpart of the road bed will be comparatively rigitland unyielding, while the portions thereof exposed to the sun will giveor yield thus permitting the ties to sink under the weightof a train,and be practicall without support except for the nails, a ter the trainhas passed. On some roads it is the practice to insert shims between theties and the rail, over the yielding portions of the track, so as tocompensate for the depres` sionof the tie, and form a support for therail.

In vthe application above referred to the construction is such that theintroduction of shims between the tics and rails is prevented by thespring clamps or clips which bind the rails solidly to the ties, and theobject of the invention is to so construct the spring clamps and other`parts, that space will be left .for the introduction of shims or wedgeswhereby the rails may be supported in alinement on ties that have beendepressed.

The accompanying drawing is a view in. cross section of a trackembodying my invention.

lVhile I do notlimit the use of my invention to any particular shape orconstruction of metal tie, I have shown it applied to :1 tie having amember extending lengthwise the rail, as disclosed in the applicationabove the depending flanges 6, which overhang lthe side edges of thetie, and with upwadly projecting flanges 7, against which thi/side edgesof the base flanges 8 of the` ail 9 abut, the top flanges 7 of thechair,'pfojeet ing slightly above the base flange of l,the rail asshown.

8a are armor plates ribbed asvshown, and resting against the insulatingmaterial at the'underside of the top. flange of the tie, and heldagainst the depending flanges 6 of the chair. These armor plates 8, areheld in place by the spring clamps'9a, which latter are shaped as shown,and are made preferablyof vanadium steel, or other hard, tough' landfinely grained steel or iron alloy, heat/treated if necessary, and of asize sufficient to withstand the strains and shocks to' which they arelsubjected. These clamps extend up and around the side edges of thechair5, and rest on the top of the latter with their upper ends above, butnot in contact the rails loose-ly seated on the chairs, but as theresultant of falls within the base of the rail, the only pressure towhich a rail is\snbjected, other than downward, is an outward one whishis hence there is, theoretically, no tendency for the rails to tip, butas the ends of the clips overlap the base flange of the rails, and areonly removed therefrom a limited distance suflicient to permit of theintroduction of shims, it will be seen that tipping to anything like adangerous extent would be absolutely prevented by the ends of theclips..

It is a well known fact that where wooden ties and spikes are used,after the first train passes over it, the spikes are drawn from the woodleaving a space between the head and the rail; also where the rail issupported at intervals as with cross ties, the rails deflect between thespaces and cause a wave action. 71th my construction the rail is outwarddisplacement by with the base flange of the rail. Thisleaves.

the wheel pressure always- This chair/ 0f the tie and 1s provided at itsside edges with .95 taken care of by th'e side flanges of the chair,

I gravity such a.

.my construction is such as to gages a Aan upwardly projecting flange ofthe chair,

free to move tothe worm action which is not the case between the woodenties and spikes. The track will move .vertically up 5 and downwithout'disturbing the ties, and

take care et all side shear.

Engineers endeavor to keep the center of 5 of-locomoftivesland carsloaded'at i height that the downward thrust is within the base of therail so there is no tendency to turn the rail over. l guard against thisside shear by the chair as used l in my construction. By thisarrangement it will be seen that if the road bed be soft in spots, itcan be supported by the introduction ofshims or wedges which willc0111-, pensate4 for part, if not all, of the movement of. the tie.

Having fully described my invention what I' claim as new and desire tosecure by Letj ters-Patent, is v 1. The'eombination of a rail, a tie, achair located thereon and provided with upwardly projecting anges, and aspring clip or clamp having .two jaws one of which venlixed support onthe underside of the Ptop fiange of the tie and the other rests on anupwardly projecting flange ofthe chair with its free end projecting oversaid latter flangefand over but not in contact with a part resting onsaid chain( 2. The combination of a' rail, a tie, a chair located.thereon and provided with .upwardly projecting flanges and a spring cliporclamp having two jaws ,one of which engages a fixed stop atthevunderside of the top fiange of the tie and the other rests on withits free end projecting over said latter flange and over but not incontact with the base iange of the rail. A

3. The combination of a rail, a tie, a chair located thereon andvprovided*` at its sides with upwardly projecting flanges and two springclips or clamps each having two jaws, one of which engages a fixedsupport on the underside of the top flange of the tie and the otherrests on an upwardly projecting flange of the chair, the .said clipsbeing located on opposite sides of said chair with their ree endsprojecting -over said latter anges' and over but not in contact with,the member resting on said chair.

4. The combination of a rail, a tie, a chair located on the tieandhaving depending flanges overhanging the side edges of the top flange ofthe tie and upwardly proj ecting flanges forming side supports tor` therail, and two spring clips or clamps each yhaving two jaws one of whichengages a v,fixed support on the underside of the top flange of the tieand the other rests on an upwardly projecting iiange ot the chair, the'said clips or clamps being located on opposite sides of the chairy withtheir ree ends projecting over said latter flanges and over but `not`incontact with the base ange of therail resting on said chair.

In testimony whereof, I have signed thisl specification in the presenceof two subscribing w1tnesses.
